| cap-assisted colonoscopy compared visibility with standard colonoscopy | Propose to perform a randomized controlled trial comparing cap-assisted colonoscopy with the standard colonoscopy to assess visibility. To see if it is easier to detect polyps, adenomas with the cap than without. This is standard procedure. Just comparing if it is better to use the cap during colonoscopy. | 4 months |
| Measure | Description | Time Frame |
|---|---|---|
| Polyp detection rate | Number of Polyps detected per procedure using the cap. To see if it is more visible. | 4 months |
| Adenoma Detection | number of adenomatous polyps detected per procedure. To see if it is more visible using the cap as to not using the cap. |
